Technical Field

The invention belongs to the technical field of freshwater fish processing, and particularly relates to a profiling rubber roller type fish scale removing device.

Background

The pretreatment of freshwater fish is the first link in the processing process of freshwater fish, and the efficiency of pretreatment directly influences the subsequent processing and the resource utilization rate. The scale removing process of the freshwater fish is an important process in the pretreatment of the scaled freshwater fish, and because the scales on the surface of the freshwater fish mostly grow in an arc line, the same type of fish has different sizes in different growth periods, and even the freshwater fish of different types has larger differences in size, so that the problems bring great difficulty to the processing of freshwater fish products.

Most of fish primary processing equipment in China is a single machine with low automation and informatization levels and simple functions, and still needs manual intervention in many links. For example, the most common way for vendors to remove fish scales is to use a steel brush to manually remove the fish scales, and better vendors use a hand-held electric scale remover. The tool has low processing efficiency, poor tool protection measure effect and easy accidental injury to workers during processing. Meanwhile, the processing environment of the tools is exposed, so that the products can be polluted while the scales are removed.

At present, some scale removing devices with higher automation degree are also available, the devices can be divided into an intermittent type device and a continuous type device according to a feeding mode, and the working principle basically utilizes the friction between scale removing parts and freshwater fish so as to achieve the purpose of removing the scales.

The intermittent fish scale removing device is used for putting freshwater fishes in batches, processing the freshwater fishes once after the freshwater fishes are loaded by the processing device, and the intermittent fish scale removing device needs to pause to put materials in the processing process and repeat the operation in a circular manner. The machine is suitable for small-batch and intermittent processing, cannot meet the processing requirement of large freshwater fish, cannot adapt to continuous processing of a production line, and is low in production efficiency.

In addition, only the gap between the rubber rollers is flexibly adjustable, and actually, the rubber rollers are contacted with the fish body or are contacted with an approximate straight line and a curve, namely, the rubber rollers cannot be completely in frictional contact with the fish body, so that the overall descaling effect is not very ideal. In addition, the flexible multi-roller fish scale removing device is not provided with a mechanism for stably conveying freshwater fish, and the rotating rubber roller is exposed outside, so that the safety performance is poor.

In one embodiment, as shown in fig. 3-4, the housing 300 has a feed chute 700 at the entrance of the loading position and a discharge chute 800 at the exit of the loading position, and both the feed chute 700 and the discharge chute 800 are inclined downward to facilitate the transportation of fish.

In specific design, as shown in fig. 1-4, the profiling rubber roller type fish scale removing device provided by the invention comprises a clamping and conveying rubber roller 200, a fish scale removing rubber roller 100, 3 pairs of sprocket transmission mechanisms, a motor and a frame, wherein the clamping and conveying rubber roller 200 is provided, 1 pair of fish scale removing rubber rollers 100 are provided, each sprocket transmission mechanism comprises an input shaft 601, six output shafts 602, an input sprocket 603, a tensioning sprocket 609, two auxiliary sprockets 610, seven sprockets including three output sprockets 605 and a chain, each output shaft 602 is provided with a gear, the motor comprises a first motor 400 and a second motor 500, the first motor 400 adopts a power source servo motor, the second motor 500 adopts a power source speed reducing motor, the frame comprises a frame 300, a hanging plate 900, a feeding chute 700 and a discharging chute 800, the frame 300 is formed by welding and assembling rectangular and circular pipes, the hanging plate 900 is connected with the frame 300 through bolts, the main purpose of the motor is to provide a suitable position for installing the speed reducing motor.

In this embodiment, 3 pairs of holding and conveying rubber rollers 200 are installed on the frame 300 along the feeding direction of the fish body, wherein 2 pairs are disposed at the inlet of the fish scale removing rubber roller 100, and the other 1 pair is disposed at the outlet of the fish scale removing rubber roller 100. Because the center distance between each pair of rollers is within the length range of the fish, namely the distance between the second fish clamping gap and the first fish clamping gap and the distance between two adjacent second fish clamping gaps are smaller than the length of the fish body, the fish body can be pushed to pass through the whole device only by the clamping and conveying of the rollers without any clamp.

The second motor 500 drives the input shaft 601 to rotate through the first coupling 607, and further drives the input sprocket 603 to rotate, under the driving of the chain, the three output sprockets 605 rotate synchronously, so as to drive the three output shafts 602 connected therewith to rotate, the three output shafts 602 are respectively connected with the clamping and conveying rubber rollers 200 through the second couplings 608, so as to drive the respective clamping and conveying rubber rollers 200 to rotate, the three output shafts 602 are engaged with the gears of the other three output shafts 602 through the gears thereon, so as to drive the other three output shafts 602 to rotate, and further drive the other three clamping and conveying rubber rollers 200 to rotate, wherein the transmission ratio of the gear transmission is 1: 1. Thus, when the speed reducing motor works, the three pairs of output shafts 602 can drive the three pairs of profiling clamping conveying rubber rollers 200 to convey the freshwater fish in the same direction. The first coupling 607 and the second coupling 608 may be implemented by a double clutch coupling.

The feeding chute 700 has a certain inclination and can provide a certain initial speed for the fish body through the power potential energy of the freshwater fish, when the freshwater fish enters from the feeding chute 700 and contacts the first pair of the clamping and conveying rubber rollers 200, then the freshwater fish is conveyed forwards and contacts the second pair of the clamping and conveying rubber rollers 200, and the attitude of the freshwater fish is horizontal and continues to move forwards under the combined action of the first pair of the clamping and conveying rubber rollers 200 and the second pair of the clamping and conveying rubber rollers 200. Then, the freshwater fish enters the fish scale removing rubber roll 100, the first motor 400 directly drives the fish scale removing rubber roll 100 to rotate through a gear transmission mechanism, the gear transmission mechanism comprises three gears which are meshed in pairs, wherein the gear on the first motor 400 is a small gear, the gears on the two fish scale removing rubber rolls 100 are large gears with the same number of teeth, the transmission ratio of the small gear to the large gear is approximately equal to three, and the transmission ratio of the large gear to the large gear is one. The freshwater fish, from which the fish scales have been removed, will continue to move forward, contact the third pair of clamping rollers, and then leave the device through the discharge chute 800.

In this example, the rotation speed of the holding and conveying rubber roller 200 is set to 100r/min, and the rotation speed of the fish scaling rubber roller 100 is set to 545r/min, that is, the rotation speed of the holding and conveying rubber roller 200 is far lower than that of the fish scaling rubber roller 100, and at the same time, because the holding and conveying rubber roller 200 can firmly hold the fish body, the fish scaling rubber roller 100 and the fish body generate rapid friction, so that the scales of the freshwater fish are removed. The fish scale removing rubber roll 100 is provided with a plurality of first barbed plates 102.2, the fish scale removing rubber roll 100 does not move elastically, and the purpose of profiling is achieved by simulating the appearance of the freshwater fish through the elastic deformation of the first elastic elements 102.1 between the first barbed plates 102.2 and the main shaft 101 of the fish scale removing roller.

The invention has the following advantages:

(1) the scale removing rubber roll provided by the invention can automatically adapt to freshwater fish with different body types when in work, and the first gill plate on the rubber roll can approximately perfectly contour the appearance of the freshwater fish, so that the scale removing rate of the freshwater fish is greatly improved;

(2) the clamping and conveying rubber roll provided by the invention is not only designed into a moon shape by adopting a profiling design, but also can self-adjust the clamping distance according to the size and the thickness of a fish body by the elastic connection of the second elastic element so as to ensure enough clamping force to stably convey fresh water fish;

(3) the power source of the fish scale removing rubber roll is a servo motor, different rotating speeds can be provided, the fish scale removing rubber roll is suitable for processing different fish species which need different rotating speeds due to different binding forces of fish scales and fish bodies, and the fish scale removing rubber roll is not only beneficial to improving the scale removing rate, but also beneficial to improving the adaptability of the fish scale removing rubber roll.
